"We paid close to $20,000 to BQ Basements to completely waterproof our basement. We still get water and they told us we need another sump pump installed at over $2,000. They guaranteed we would not get water after installation. Be aware they do not stand behind their work or honor warranties."

"Working with DJ from Groundworks (Select Basement) has been an outstanding experience. After struggling with various contractors who either failed to resolve our water issues or were unprofessional, DJ and his team truly stood out. DJ was incredibly helpful, patient, and responsive throughout the entire process. Our home is a ranch with 225 linear feet around the perimeter, and while other contractors insisted on installing a French drain for the entire length, DJ recommended a more targeted approach. He proposed installing the French drain for just 80 linear feet, focusing only on the areas where water intrusion was likely. His thorough explanations and prompt responses to all our questions were greatly appreciated. The workers arrived on time, maintained a clean work environment, and completed the job as promised. If we could give 10 stars, we would! Groundworks is a highly professional and honest company that didn't try to inflate the scope of work to charge us more. We wholeheartedly recommend them."

"It's been 10 years since MC installed my concrete and it still looks amazing. I recently asked Tony touch up the silicone joints in certain areas that got beaten up from the weather and his response was great. Repaired like new. The overall job back in 2008 was absolutely amazing, he hires only the best masons of course, who know nothing but perfection. The equipment is top of the line and his management of the job is the best. He oversees the entire project to ensure its done absolutely perfect from start to finish. Usually done within one day your property gets a much needed face-lift by the mid to late afternoon. Please understand that the level of service is amazing, not rushed, the crew along with trucks and equipment arrive ready to work and transition your worn cracked old concrete into a stunning new pitch perfect masterpiece, with the MezzaCappa Swirl! Rock solid indeed. You're not likely to find a service that can meet his level of performance, quality and PRICE! I highly recommend you consider and book MC for your concrete, stone, and masonry work, you will not be disappointed!"

"Walt, Max, and the whole crew were absolutely amazing. This was a HUGE project. We basically had no foundation on the back/ side of our house and the 2nd floor overhang was poorly supported. Prior to us purchasing the house the previous owner added a very large addition on top of a very old and poorly constructed “house” . The inspection at purchase did not uncover the issues that we found about two years after when all of the cosmetic touch ups wore off. Walt’s crew ( Supervised by Max) replaced the foundation wall , added piers under the house, replaced all of the floor joists along with new piers, beams, and headers on the 40ft span at the back of the house. This is just some of the larger items because I would be here forever if I listed everything they had to do. Walt kept us informed during the whole project. From start to finish we were on the same page. The house had so many hidden issues but the crew worked through all of it. The price was very reasonable and less then all of the other estimates from competitors. We didn’t have a bunch of surprise increases along the way. He didn’t try to scare us or sell us anything we didn’t need. They are honest and reliable. The results were amazing and so far beyond our expectations !!! They are all so talented. We couldn’t be happier with our choice of contractors!! They have been done for almost a week and we miss them being here already. I will recommend them to everyone."
